LAHORE - A 20-year-old girl allegedly shot her elder brother dead, the only breadwinner of the family, when the later reprimanded her for developing illicit relations with a youth in Qilla Gujjar Singh police limits early on Monday. Police however, managed to trace the killer girl through her mobile phone and arrested her from Nasirabad police limits. The police recovered the pistol from her possession and also some valuables including cash and gold ornaments worth over Rs 500,000 which she had taken away from her house soon after the incident. The pistol was owned by his diseased brother, Abbas Waheed. It has been learnt that the police took into custody paramour of the girl identified as Muhammad Usman. In her statement to the police Sidra told she had fallen in love with a boy, Usman, a resident of Nasirabad area. She had several times asked her brother Abbas to avoid from interfering in her love affair and also warned him that it was not possible for her to leave the boy, she further stated. She however, denied the involvement of her paramour in the murder incident of her brother and told the police that she took the decision of killing Abbas alone and murdered him for torturing her paramour in her presence, an investigation officer Asghar Ali told this scribe. Sister of three, Sidra was unhappy over the repeated involvement of her brother Abbas Ali in her lover affair with the boy, Sidra's mother told the police. The deceased, Abbas had taken it serious when he first time came to know about the relationship of his sister with a boy of Nasirabad area and asked her to refrain from such activities in future. But she ignored his brother's warnings. A day before the incident, Abbas got furious when he was informed about another meeting of his sister with the said boy and visited the site of their meeting where he exchanged hot words with the boy and also scuffled with him in the presence of his sister. He then took his sister back to home and snatched her cell phone from her, which she had been using for contacts with her paramour. Almas Bibi, mother of victim Abbas told the police that Sidra took it on heart and exchanged hot words with her brother late night on Sunday and she also threatened her brother of dire consequences. She immediately intervened and resolved the matter between the brother and sister, she further said. Early morning on Monday, relations between Sidra and Abbas were quite normal and after Sehri both went to their beds, she said. Almas said after some times she heard the voice of a bullet shot in the room of her son and immediately rushed to the spot. As soon as she entered the room she found Abbas lying in pool of blood with a bullet injury on his forehead. She called the neighbours for help who reached the spot and took the injured to the Mayo Hospital but Abbas succumbed to his injuries on the way. Almas Bibi said the first idea which came to her mind was about the suicide attempt of her son following his sister's story of love affair with the boy but the actual situation revealed when she found her daughter was missing from her house after the incident. Cupboard of some rooms were also found unlocked and she found that some valuables including cash and jewelry were also missing. The police reached the house on the call of a neighbour and shifted the body to the city morgue for autopsy. A local resident told the police that the killer girl's temperament was not normal and she used to quarrel with her neighbours over petty issues. Many had complained her mother about her rough attitude but to no avail. It is pertinent to mention here that the victim family was already in trouble as the deceased's father, Sheikh Waheed and two elder brothers had died in a tragic incident in the past. One of his two brothers died of cancer while another in a road accident and their father also died following a disease. Abbas was the only breadwinner of his family. He was a milk seller. His two elder sisters were married while Sidra was still unmarried.   The police said that the arrested girl had been sent behind the bar and a case was registered on the complaint of her mother.
